Gas Processing Facility
Our proposed gas processing facilities on Barrow Island include an LNG plant, condensate handling facilities, carbon dioxide injection facilities and associated utilities.
The LNG plant will comprise three trains capable of producing a total of 15 million tonnes per annum. About three LNG shipments are expected to leave a dedicated LNG loading jetty each week.
Construction and commissioning of the trains will be staggered over 18 months as the 300 hectare development envelope limits our working area. We're also committed to managing the number of people working on Barrow Island to safeguard its quarantine program.
Pivitol to our commitment to the environment will be our use of modularisation to build the trains. By doing this, all the components will be pre-fabricated and assembled off site into transportable parts – significantly reducing our impact on the Island.
A domestic gas phase, progressively supplying up to 300 terajoules per day, will be an integral component of the foundation project.
The domestic gas pipeline will run from Barrow Island to a "tie-in" with the Dampier-to-Bunbury natural gas pipeline. This gas will play a vital role in meeting future energy needs for Western Australia.
Our gas processing facilities will be based on the gas treatment and liquefaction processes selected during the design basis for the facility. An integral component of the facilities will be our world-leading carbon dioxide injection and storage technology. Watch the video.
Typical Gas Facility Process
The Gorgon gas facility process will separate gas and condensate (light oil) received from the Gorgon gas fields. After separation from the gas, the condensate will be stabilised prior to shipping to market. The gas component of the stream will then be treated to remove carbon dioxide, hydrogen sulfide, trace amounts of mercury and water vapour. At this point the gas can be liquefied for export as LNG.
The stages of processing are outlined below.
